A COVID-19 vaccine candidate made of tiny artificial particles could be more powerful than other leading varieties at triggering a protective immune response.
When the team injected mice with the nanoparticle vaccine, the animals produced virus-blocking antibodies at levels comparable to or greater than those produced by people who had recovered from COVID-19. Mice that received the vaccine produced about ten times more of these antibodies than did rodents vaccinated only with the spike protein, on which many COVID-19 vaccine candidates rely.
The vaccine also appears to produce a strong response from special immune cells that help to mount a fast defense after infection with SARS-CoV-2

Researchers identified some of the most potent and diverse antibodies discovered to date that neutalize SARS-CoV-2, targeting multiple regions on the viral spikes. Potent antibodies could be produced in the lab and given to people to prevent or treat coronavirus infection.
